See, here the beatitude is so simple and so without mode that therein all essential gazing, inclination and distinction of creatures pass away. For all spirits thus raised up melt away and are annihilated by reason of enjoyment in God’s essence, which is the superessence of all essence. There they fall away from themselves and are lost in a bottomless unknowing.

John Ruysbroeck, in The Little Book of Enlightenment by Bernard McGinn in The Essential Writings of Christian Mysticism
